anthrazit: sovereignty score and 8 European alternatives

anthrazit is a cloud platform for Swiss municipalities and cities, developed by anthrazit ag in Zurich. It combines apps for residents with a content management system in which the administration enters its content once. The apps range from Gemeinde-News and citymobile to an individually branded anthrazit app. Optional modules cover news, events, digital information screens, places on a map, photos, measurement data, parking spaces and personalised information. According to the vendor, the platform works alongside existing websites and tools.

anthrazit ag is headquartered in Zurich, Switzerland. The vendor states that the platform runs in a Swiss data centre and that data never leave Switzerland; its privacy policy refers to the Swiss data protection act and to regular backups. Switzerland is not an EU member but is an EFTA country with an EU adequacy decision. The company's ownership is not stated and no self-hosted option is described. A municipality that wants to keep control of its data should ask which hosting provider is used and how content can be exported.

Why digital sovereignty matters with anthrazit

anthrazit is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

anthrazit hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

anthrazit is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs anthrazit together with your other vendors and gives a total score, a heatmap and the main risk drivers.
